  • Patent number: 7618804
    Abstract: There is provided a method for producing L-threonine, L-valine, L-proline, L-leucine, L-methionine and L-arginine using a bacterium belonging to the genus Escherichia wherein the L-amino acid productivity of the bacterium is enhanced by enhancing the activities of the proteins coded by the b2682 and b2683 genes, or the protein coded by the b1242 or b3434 gene.
    Type: Grant
    Filed: May 14, 2008
    Date of Patent: November 17, 2009
    Assignee: Ajinomoto Co., Inc.

  • Patent number: 6737255
    Abstract: The present invention provides an isolated DNA molecule encoding a small subunit of acetohydroxy acid synthase isozyme III originating from Escherichia coli and mutants of Escherichia coli acetohydroxy acid synthase isozyme III, which are free from inhibition by L-valine an can catalyze the conversion of: (a) pyruvate to &agr;-acetolactate and (b) &agr;-ketobutyrate and pyruvate to &agr;-aceto-a-hydroxybutyrate. The present invention also provides methods for producing L-valine by fermentation of a bacterium harboring the novel DNA molecule and/or expressing the mutant acetohydroxy acid synthase isozyme III.

  • Publication number: 20020037562
    Abstract: A method for producing L-valine comprising the steps of cultivating the bacterium harboring a DNA coding for actohydroxy acid synthase isozime III originating from Escherichia coli which is free from a inhibition by L-valine and has an activity to catalyze two reactions to generate &agr;-acetolactate from pyruvate and &agr;-aceto-&agr;-hydroxybutyrate from &agr;-ketobutyrate and pyruvate, producing and accumulating L-valine in the culture medium, and collecting L-valine from the culture medium.
